Is there anything the colonists or british could have done to avoid the revolution

"Yes and no. I do not believe British efforts to create a true empire could have worked. The colonies had for many years been moving toward autonomy and were unwilling to accept the sort of imperial structure and dependency the British government tried to establish at the end of the Seven Years War, especially as there was no credible military threat on the North American continent to force them to rely on British arms. On the other hand, I could easily see an arrangement, something like dominionship, under which Americans would have remained part of the empire. If offered such an arrangement in the first months of the war, I believe most Americans would have happily accepted it."
